  • the fluid treatment apparatus is indicated by the reference character 10. As illustrated, one longitudinal end of the apparatus has a strand inlet opening 11 for receiving the strand material to be processed.
  • the advancing strand material travels through an elongate strand processing duct 12 and exists the apparatus at the opposite end of the apparatus via a strand outlet opening 13.
  • Pressurized fluids are supplied to the fluid treatment apparatus 10 via fluid supply ports 14,15 and spent fluids exit the apparatus via fluid discharge ports 16,17.
  • the treatment fluids act upon the strand material to impart texture or crimps, as explained more fully below.
  • the fluid treatment apparatus includes body member 21 having a substantially planar upper surface.
  • the apparatus also includes a cover plate 23 having a substantial planar lower surface. Sandwiched between the upper surface of body member 21 and the lower surface of cover plate 23 is a stack of laminae indicated generally by the reference character 30.
  • the polylaminar stack forms the elongate strand processing duct 12.
  • the fluid supply ports 14,15 (FIG. 1) communicate with laterally extending fluid supply bores 25,26 formed in the body member 21.
  • a pair of laterally spaced apart, upwardly extending fluid supply bores 27a, 27b (FIG.
  • the fluid supply bores 27a, 27b supply pressurized fluid to a pair of strand advancing jets 31 (FIG. 3) located adjacent the strand inlet opening 11, which serve to propel the strand material into the elongate strand processing duct 12.
  • the fluid supply bores 28a, 28b supply pressurized fluid to a pair of strand retarding jets 32 located adjacent the strnd discharge opening 12.
  • the cross sectional area of strand processing duct 12 varies along the length of the duct.
  • the duct is of a relatively small cross section sufficient to admit the advancing strand while limiting any significant discharge of pressurized fluid from the entrance end 11.
  • the duct then increases in breadth for a distance along an entrance zone 33 (FIG. 3) after the strand advancing jets 31.
  • the duct is of a generally similar cross section in an exit zone 34 at the downstream extremity of duct between the strand retarding jets 32 and the discharge end 13.
  • a crimping chamber or zone 35 which is of increased breath and height.
  • the crimping chamber 35 is provided with perforations 36 which allow fluid from the strand advancing jets 31 and the strand retarding jets 32 to exit the crimping chamber to the discharge ports 16,17.
  • strand material such as a yarn
  • a heated fluid such as air or steam
  • a cooling fluid such as compressed air
  • the crimped strand material is withdrawn from the discharge end 13 of the apparatus.
  • the elongate strand processing duct 12 is formed by the cooperating laminae of the stack 30.
  • the stack 30 includes a central lamina 40 which has an elongate longitudinally extending slot-like opening formed in a medial portion thereof which extends from one longitudinal end of the lamina to the opposite end.
  • the slot-like opening defines the longitudinally extending side walls of the elongate strand processing duct 12.
  • the central lamina 40 is of a unitary one-piece construction formed by machining the slot-like opening in a plate of substantially uniform thickness.
  • the central lamina 40 is symmetrical about a line of symmetry extending longitudinally along the slot-like opening, with its two longitudinal halves 40a, 40b being joined together by web portions 41 of reduced thickness.
  • intermediate laminae 42 On opposite sides of the central lamina 40 are intermediate laminae 42. As illustrated, the intermediate laminae have a central opening 43 formed therein which overlies the crimping zone 35, thereby providing the increased height dimension in the crimping zone. Outer laminae 44 are located on oppostite sides of the intermediate laminae 42 and adjacent the body member 21 and cover plate 23 respectively. Perforations 36 are formed in the outer laminae 44 overlying the openings 43 in the intermediate laminae 42.
  • the body member 21 and the cover plate 23 are mounted so that they can be moved apart from one another.
  • the central lamina 40, the underlying intermediate lamina 42, and the underlying outer lamina 44 are secured as a unit to the body member 21 by suitable means, such as screws 47.
  • the uppermost intermediate lamina 42 and the uppermost outer lamina 44 are secured to the cover plate 23 by suitable means, such as screws 47.
  • FIGS. 5 and 6 illustrate some alternate constructions for the central lamina 40.
  • the central lamina 140 is discontinuous, comprising two separate halves 140a, 140b. The cooperating halves are mounted in spaced apart relation to partially define the elongate strand processing duct 12.
  • the central lamina 240 is formed from a single unitary plate, with the elongate slot-like opening and jets being formed in the plate by machining.
  • the entry end 211 and the discharge end 212 are defined by bores formed in the plate and extending along the longitudinal axis of symmetry. This embodiment has the advantage of being somewhat easier to manufacture, but it requires that a free end of the strand be accessible for threading into the entry end 11 of the elongate strand processing duct 12.
  • FIGS. 10-13 One possible such arrangement is illustrated in FIGS. 10-13.
  • elements which correspond to those previously described in the previous embodiment will be identified by corresponding reference numbers, with prime notation and/or letter suffixes added.
  • the strand treatment apparatus 10' illustrated in FIG. 10 is designed for processing four strands simultaneously.
  • the apparatus has a body member 21' having substantially planar upper and lower surfaces. Cover plates 23' are located adjacent the top and bottom of the apparatus. Sandwiched between the upper cover plate 23' and the upper surface of body member 21' is a first stack 30' of laminae, while a similar stack 30' is also sandwiched between the lower surface of the body member 21' and the upper surface of the lower cover plate 23'l.
  • FIG. 11 illustrates the construction of the central lamina 40' used in each stack. As illustrated, it is provided with a pair of longitudinally extending slot-like openings which form a pair of side by side elongate strand procesing ducts 12'.
  • the fluid supply ports 14',15' and associated laterally extending fluid supply bores 25',26' serve both the upper and lower stacks of laminae.
  • a common discharge port 17' extends laterally through the body portion, and discharge ports 16' are formed in the upper and lower cover plates 23'.
  • the apparatus shown in FIG. 10 can be readily threaded without requiring the free ends of the strand material by mounting the body member 21' in a stationay position and mounting the upper and lower cover plates 23' so that they can be moved slightly apart from the body member 21' to provide access to the elongate strand ducts 12'.
